S32K148 ftm resolver ABZ

Hi all,

I have a question regarding the S32K148 and its ability to read ABZ signals from a resolver.

PTD10>>FTM2_QD_PHB

PTD11>>FTM2_QD_PHA

PTD12>>FTM2_CH2

I’m using the FTM Quadrature Decoder (QD) function to capture the A and B signals, and I would like to clear the FTM counter when the Z signal rises, in order to ensure that any errors are cleared.

Is it correct to configure PTD12 as an input capture pin for this purpose?

Thanks,

Leon

Hi@Leon06

From your description, it is not necessary to set PTD12 as input capture.

It should also be possible to set it as GPIO port edge interrupt, which seems simpler.
